Has anyone used Bar Keepers Friend for cleaning various parts while shopping out their game? Is it too harsh of a product, or is it ok to use? From what I can tell, it's basically an abrasive that will take a microscopic top layer off whatever you are using it on, so that's why I'd want to be cautions.
I've used it on ball guides and other small metal pieces like that before, but figured I'd check before continuing to use it.
